DALLAS (CBSDFW.COM) – A domestic abuse case — described by police as one of the worst that they had ever seen — is winding down in Dallas on Wednesday. Both the victim and the defendant have already testified during the trial, and the defendant, Jose Arreola, is expected to be back on the witness stand again. Then, jurors will have to decide who is telling the truth.

Arreola said that his ex-girlfriend was the aggressor in the case. The 34-year-old’s testimony was laced with profanity. When he testifies again, he is expected to continue explaining that the victim, Maria Escamilla of Lancaster, came at him during a number of altercations.

Escamilla told the court that Arreola was a “good friend” when they met in 2008. But a year later, their relationship became abusive. “He pushed me to the ground and then dragged me by the hair,” she testified last week. “He was hitting me on parts of my body. He then grabbed a curling iron and started hitting me with it.”

The victim was stabbed multiple times, suffering serious injuries to her face, hand and groin. She was listed in critical condition when she arrived at Methodist Hospital in March 2011. Prosecutors called this a case of torture, saying that they had never seen a victim endure such abuse and survive. She has since recovered from her injuries.
